The StabiliTrak

®

light will

flash on the instrument
panel cluster when
the system is both on
and activated.

You may also feel or hear the system working; this
is normal.

The traction control disable
button is located on the
instrument panel below the
climate controls.

The traction control part of StabiliTrak

®

can be turned

off by pressing and releasing the StabiliTrak

®

button

if both systems (traction control and StabiliTrak

®

) were

previously on. To disable both traction control and
StabiliTrak

®

, press and hold the button for five seconds.

Traction control and StabiliTrak

®

can be turned on by

pressing and releasing the StabiliTrak

®

button if

not automatically shut off for any other reason.

When the TCS or StabiliTrak

®

system is turned off,

the StabiliTrak

®

light and the appropriate TCS off

or StabiliTrak

®

off message will be displayed on the

DIC to warn the driver. Your vehicle will still have
brake-traction control when traction control is off, but
will not be able to use the engine speed management
system. See “Traction Control Operation” next for
more information.

When the traction control system has been turned off,
you may still hear system noises as a result of the
brake-traction control coming on.

It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if your vehicle is stuck in sand, mud, ice
or snow, and you want to “rock” your vehicle to
attempt to free it. It may also be necessary to turn off
the system when driving in extreme off-road conditions
where high wheel spin is required. See If Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow
